No Politics, no grand-standing. Just support and reverence.
Given that Bale is a Brit and only in his 30s, I suspect he may have a little difficulty grasping our gun laws, and his international celebrity might make him think he needs to make a political statement.
But it appears he didn’t. He just met with the injured and gave his respects to the dead. He didn’t have to do this, we owe him nothing, but he realizes that those people in that theater were there to see him, and that was obviously important to him.
